Abstract
Abstract The catalytic properties of hydrotalcite‐based Cu/Zn/Al mixed oxides prepared by the incipient co‐precipitation method, in which various metals were doped through impregnation, were comparatively tested in the steam reforming of methanol (SRM). In addition, the catalysts were characterized in detail by a series of follow‐up surface techniques. Moreover, strong interaction and synergism between Ru and Cu species noticeably promoted methanol conversion and improved catalytic performance. Furthermore, an SRM reaction mechanism is proposed that rationalizes the relationship between copper dispersion on the surface and the size of the copper/oxygen interface where formed intermediates rearrange.
